Beschreibung

Blue and red light plays a critical role in plant photosynthesis, morphology, and stomatal regulation (opening and closing of tiny pores on their leaves), making precise spectral control essential for greenhouse cultivation. UV-to-blue phosphors together with blue-to-red phosphors enable the use of UV-part of sunlight while delivering plant-optimized spectra. As a result, advanced phosphors can contribute to increased crop yield, improved plant quality, and lower energy consumption in controlled-environment agriculture.
This Master’s project focuses on the development and optimization of blue- and red-emitting light-conversion phosphors for greenhouse lighting applications. Particular emphasis is placed on Eu2+, Ce3+ and Mn2+ activated host lattices that provide favorable crystal environments for efficient blue and red emission. After synthesis, the student will carry out a comprehensive characterization of the materials, covering both structural and optical properties.
The structure and morphology of the synthesized materials will be investigated using: X-ray diffraction (XRD) to identify crystal structure and phase purity; and scanning electron microscopy (SEM) to study particle size and morphology. These techniques provide insight into how synthesis conditions influence material structure.
The optical performance of the new phosphors will be studied using: Optical absorption measurements; Photoluminescence spectroscopy in the NIR range; Photoluminescence quantum yield measurements: and Luminescence lifetime analysis. This will allow the student to evaluate efficiency, emission mechanisms, and energy transfer processes in the materials.
This Master’s project is ideal for students who are interested in advanced materials with real technological relevance and who want to gain hands-on experience in both synthesis and characterization. The project provides a solid foundation for careers in materials development, optoelectronics, and sensor technology, as well as preparation for PhD-level research.
